 can you refresh my memory by telling me what the law of levers is?

anonymous · Answer

This is what it say on my lesson plan.... May help?
Mass is the term used in science for what we commonly think of as weight. The weight on one side of the fulcrum times the distance from the fulcrum must be equal to the weight on the other side times the distance.

alexwee123 · Answer

oh then we can derive a formula out of this
M=mass
D=distance from fulcrum
so M1D1=M2D2

alexwee123 · Answer

so using the info given 
M1=x
M2=53lbs
D1=4.5ft
D2=6ft

alexwee123 · Answer

plug that into the "formula"
